An adiabatic vessel contains 1000 g of liquid aluminum at 717°C. Calculate the mass of Cr203 at room temperature, which, when added to the liquid aluminum (with which it reacts to form Cr and Al203), raises the temperature of the resulting mixture of Al203, Cr203, and Cr to 1662 K. www (0 = 16.0; Al = 27.0; Cr = 52.0 g/atom) Given Thermodynamic data: Table 1.
